SPECIFICATION forming part of Letters Patent No. 763,452, dated June,28,1904.

Application riled December 13,1900. Serial No. 39,669. (No model.)

To all whom it may concern..-

type-writing machines; and the object is toprovide a type-writingmachine of comparatively simple construction so arranged'that thetype-carrying bars and operating-levers may be moved to printingoperation by a very little pressure and upon release bequickly returnedto their normal position.

I will describe a type-writer embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indieatecorresponding parts in all the figures.

Figure 1 is a rear elevation of a type-writer embodying my invention.Fig. 2 is a sectional elevation of the same. Fig 3 is a View of a blankfrom which certain links are formed. Fig. 4 is'a view of a formed link.Fig. 5 is a detail view of the type bar and lever mechanism, and Fig. 6is a perspective view showing bearings in the finger-levers andconnections.

Referring to the drawings, 1 designates the frame of the machine,comprising a base 2, the front uprights 3, the rear uprights 4, and thetop plate 5. Secured in the forward portion of the frame is anarc-shaped plate 6, to which the type-bars 7 are fulcrumed. This plate 6is longitudinally curved on its under side, so that on the operation ofthe type-bars each one will be thrown to the center for printing and toreduce the friction of the type -bars to a minimum. They are mounted toswing on a rod 8, attached to the plate 6, and having portions extendedslightly into kerfs formed in the lower edge of said plate 6, the sidewalls of these kerfs forming guides for the typebars andpreventing anypossible lateral movement thereof during their up-and-down movements.The type bars have rearward and downward projecting portions 9, whichhave link connections 10 with vertical portions 11 of angle levers, thelower or substantially horizontal portions 12 of which have linkconnections 13 with the finger-levers 14. At the angle portions theseangle-levers are mounted to swing on a wire or rod 15, attached to acomb-like bar 16, secured at its ends to the main frame. The side wallsof the spaces in this comb-like bar form guides for the anglelevers andprevent lateral movement thereof, and as the bearing of said bars is butslight within said recesses there will be but little friction. As afurther means for preventing lateral or'torsional movement of theangle-levers relatively to the type-bars and to the finger-levers thelinks 10 and 13 are of a novel form. The blank for each link is made substantially in the form of the letter H, as indicated in Fig. 3, and whenthe side members are turned to the position indicated in Fig. 4 the saidside members will present flat surfaces to the parts with which theyengage.

The inner ends of the finger-levers 14 are pivoted on a wire or red 17connected to the forward side of a comb-plate 18, the ends of which areattached to the frame of the machine. The ends of the levers 14 extendbut slightly into the spaces of the comb-plate, so that very littleresistance is presented and the bars are prevented from torsionalmovement. The forward portions of the finger-levers are guided in slotsformed in a plate 19, attached to the frame of the machine, and ofcourse upon the outer ends of these linger-levers are finger-piecesbearing the characters to be printed. Connected near the rear end ofeach finger-lever and forward of its pivotal point is the lower end of aspring 20, the upper end of which is connected to an interiorlythreadedsleeve 21, movable through an opening in a bar 22, attached to the frameof the machine, and engaging in this threaded sleeve is anadjusting-screw 23, the head of which bears upon the upper side of thebar 22. By manipulating the screw 23 it is ob-
